SCADA commissioning
Verify that what happens in the field is accurately represented at the operator interface.
- Point-to-point signal verification
- Alarm, status, and analog checks
- Command and indication validation
SCADA COMMISSIONING & INTEGRATION
From field signal.
To clear control.
SCADA, solar, and power plant control systems. From inverter integration to utility interfaces, bring your project from configuration through verification and commissioning.

Purposeful integration. Methodical commissioning.01 / WHAT WE DO
The connection between
your field and your control room.
Commissioning and integration support across utility SCADA, solar plants, protection and controls, and PPC systems.
Systems integration
Bring field devices, controllers, and supervisory systems together with a consistent approach.
- RTU, PLC, and IED integration
- SCADA database and point mapping
- HMI configuration support
Communications & troubleshooting
Work through the connections and configurations that keep useful information moving.
- Device communication checks
- Data quality and polling review
- Signal-path troubleshooting
Solar witness testing
Support solar project acceptance with coordinated witness testing, functional verification, and clear test records.
- Witness test preparation and support
- Observed response and indication checks
- Results, discrepancies, and retest tracking
Protection & controls verification
Verify protection and control functions against approved project settings, logic, and test procedures.
- Trip, permissive, and interlock checks
- Relay status and alarm verification
- Control logic and SCADA indication checks
Power plant controller systems
Integrate and verify PPC systems across the plant, connecting inverter-level operation with plant-level supervision and control.
- Inverter-to-PPC communications and mapping
- Setpoint, feedback, and response verification
- PPC-to-SCADA and external interface checks
On-site commissioning services
Hands-on support at your facility to set up solar inverters, integrate the PPC, and verify the complete plant control path.
- Inverter setup and communications configuration
- PPC integration, point mapping, and setpoint checks
- Field testing, troubleshooting, and handover
CUSTOM RTAC PROGRAMMING & SOLAR PLANT CONTROL
Your plant.
Your operating strategy.
Custom SEL RTAC project files and power plant control systems built around your equipment, site requirements, and operating preferences.
Coordinate solar inverters, site metering, SCADA, and utility interfaces through a unified control system. Choose manual operator control or fully automatic operation, with project-specific limits, communications monitoring, fault handling, and commissioning verification.
Automatic voltage regulation
Adjust reactive power using point-of-interconnection voltage feedback, with configured targets, deadbands, and operating limits.
Power factor control
Regulate toward leading, lagging, or unity power factor targets within configured plant and inverter capabilities.
Reactive power control
Control site reactive power to a specified target, distributing requests across qualified available inverters.
Intelligent inverter allocation
Manage output limits, curtailment, and ramp rates. Allocate power across available inverters and redistribute demand within their operating capabilities.
Operator-directed control
Provide manual setpoints, start/stop commands, and inverter participation controls while retaining configured permissions and interlocks.
Coordinated site operation
Support qualified automatic startup, continuous output adjustment, and controlled inverter return when communications, permissives, and operating conditions allow.
Connected data. Clear operating decisions.
Integrate meters, weather stations, inverter diagnostics, alarms, and utility or PJM telemetry. Configure communications-loss responses, fault handling, and recovery behavior for the site’s operating requirements.
CUSTOM HMI DESIGN & INTEGRATION
Built to your specifications.
For local or remote control.
PollRate Systems develops custom human-machine interfaces (HMIs) around the way you operate. Bring plant status, trends, alarms, and controls into a clear interface for local operators or authorized remote users.

Interface architecture and test scope are tailored to each project.02 / HOW WE WORK
Clear scope.
Deliberate testing.
Practical handover.
Every project has its own equipment, requirements, and operating constraints. The work starts by understanding yours.
- 01
Understand the system
Review the scope, device interfaces, point lists, and commissioning requirements.
- 02
Connect and configure
Align communications, point mapping, and operator displays around the project’s needs.
- 03
Test and resolve
Work through agreed test procedures, document findings, and address discrepancies.
- 04
Document and hand over
Capture configurations, test results, and outstanding items for a clear transition.
